D) Endocytosis is a transport mechanism that utilizes energy.
Endocytosis is an active transport, a biological process in which <span>molecules from outside the cell (proteins for example) are passed through the cell membrane and put into the cell. This process requires energy.
The other transport mechanisms, osmosis, diffusion and facilitated diffusion are processes that do not utilize energy. </span>
Answer:
Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules
May i have choices but <span>Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure on this trait, the heights of individuals in a population would vary, with most individuals being of an average height and fewer being extremely short or extremely tall. However, when selection pressures act on a trait, this distribution can be altered.</span>
Answer:
The correct answer is: A--> P--> E.
Explanation:
Translation is a key process made by the cell, from which proteins are synthesized. In order to function, translation needs several types of RNA: mRNA provides the "code" that will translate into a protein, rRNA forms the ribosome where the translation is going to take place, and tRNA provides the amino acids.
Elongation goes through A--> P--> E.
The correct answer is A plant tissue samples should be free of soil particles
